"There has been a coup. Ahmedinejad and the security services have taken over. The Supreme Leader has been preserved as a figurehead, but the structures of clerical rule have effectively been gutted and are being replaced by a National Security State. Reports that facebook, twitter, text messaging and foreign TV broadcasts have been blocked, that foreign journalists are being expelled and that large concrete roadblocks (the kind that require a crane to move) have appeared in front of the Interior Ministry all feed a sense that what we are now seeing was pre-planned. Underlying this is the theory that Ahmedinejad and the people around him represent a new generation of Iranian leadership. He and his colleagues were young revolutionaries in 1979. Now in their 50s they have built careers inside the Revolutionary Guard and the other security services. They may be committed to the Islamic Republic as a concept, but they are not part of its clerical aristocracy and are now moving to push the clerics into an essentially ceremonial role. This theory in particular seems to be gaining credibility rapidly among professional Iran-watchers outside of the country."
